Well, as you can see, our locks mostly are liner and frame locks. Liner and frame lock both have good and bad side, not so prefect but still safe and fun enough and cost less. A compeny should consider the costes so less cost might have a big weight of defining the 'Best' for a knife maker, that was the answer i guest. However, Kizer not only wanna be a knife maker but also wanna be a friend and family to accompany and feedback those who follow and support us. So, as a friend and family of you guys, our definition of 'Best' is your joy and safety. Then here we are, created a discussion thread of locking mechanism and taking notes about what you guys think is the best for you and improving ourselves.
Hope you like the answer which came from our heart. And hope we have the chance to accompany you and bring you joy.
